本文对热处理条件下U－10％Zr合金马氏体相的形成和结构进行了研究．结果表明，合金试样在单相γ区和γ1+γ2混溶区水淬得到正交结构的马氏体α’相，而在β+γ2和α+γ2相区水淬可获得塑性较好的单斜结构的马氏体α“相；合金硬度防不同马氏体相的形成而变化.随着合金中马氏体相的出现，晶格参数a略有诂小，而b明显增大．
In this paper, the formation and structure of the martensitic phase of U-10% Zr alloy under heat treatment were studied. The results show that the martensitic α ’phase of the orthorhombic structure is obtained by water quenching of the alloy sample in the single-phase γ region and the γ1 + γ2 miscible region, and the plasticity is obtained by water quenching in the regions of β + γ2 and α + γ2 Of the monoclinic martensitic α ”phase; the hardness of the alloy varies with the formation of different martensite phases. With the advent of the martensite phase in the alloy, the lattice parameter a is slightly smaller and b significantly increased Big.
